Solar Activity was at high levels. Region 9672 (S18W27) produced a X1/3B flare at 25/1502 UTC with associated Type II (est. velocity 900 km/s) and Type IV events observed. SOHO/LASCO imagery indicate a full halo CME with a plane of sky speed of 884 km/s. Region 9672 also produced three minor C-class flares. Region 9678 (N08E20) has grown significantly in the last 24 hours. This region has increased in area coverage, spot count, and magnetic complexity to 300 millionths, 35 spots, and Beta-Gamma-Delta configuration, respectively. Other activity on the disc was six minor C-class flares most of which came from Region 9672 and 9678. New Region 9681 (S25E05) and Region 9682 (N09E70) were numbered today.

Solar activity is expected to be at low to moderate levels with a chance for an isolated high condition. Region 9672 and Region 9678 both have the potential of producing a major flare. Both of these regions are active and magnetically complex. New Region 9682 is just rotating on to the disc but already appears to be a large and potentially complex region.

Geomagnetic activity was at quiet to unsettled levels. Shock arrival from the two CMEs (M6/2N on 22/1502 UTC and X1/2B on 22/1759 UTC) occurred at 25/0850 UTC with a sudden impulse of 22 nT recorded on the Boulder magnetometer. A north directed Bz component to the interplanetary magnetic field resulted in only unsettled conditions.

Geomagnetic activity is expected to be at quiet to major storm levels. Quiet to active levels are expected on day one of the period. Analysis of the X1/3B full halo CME on 25/1502 UTC indicates that shock arrival is expected late on day two or early on day three of the period. Shock arrival is expected to produce unsettled to minor storm levels for day two and three of the period. Isolated major storm levels are possible particularly at higher latitudes.
